On October 1, ARM Holdings rose 3.26% in pre-market trading, trading at approximately $298.73/share, with turnover of $17.908 million. The semiconductor sector continued its broad-based recovery following a sharp selloff earlier in the week.

On the news front, ARM is extending a rebound that began after the stock plunged over 8% on September 28, when OpenAI announced a pause on training and testing of its most advanced AI model, sparking concerns over the outlook for AI infrastructure spending. The broader Philadelphia Semiconductor Index fell 3% that session. Since then, the sector has entered a recovery phase, with ARM surging nearly 6% on September 29 and continuing to build on gains. Citi recently raised its CPU market forecast significantly to $237 billion by 2030, up from $137 billion, citing Agentic AI-driven server CPU demand as the fastest-growing segment. ARM has also announced a new computing platform targeting Agentic AI and an AGI CPU product line, reinforcing its medium- to long-term growth narrative. Notably, options activity has reflected mixed sentiment, with a $192 million deep in-the-money put appearing on September 30, while sector peers including Intel, AMD, Broadcom, and NVIDIA all posted gains in the current session.
